PLAINVILLE prefixes in area code 785

NANPA records 4 assigned NXX blocks to rate center PLAINVILLE in area code 785, 0.6% of the 726 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 4 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (1), SOUTHWESTERN BELL (1), TELEPORT COMMUNICATIONS AMERICA, LLC - KS (1). The earliest assignment on record here is 2003-04-03 and the most recent 2021-06-10. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 812, 860, 959 – overlay codes cover the same geography, so a rate center is served by all of them.
